Alhamdulillah takda bleeding, tu dah bagus sign! Apa yang kak rasa tu likely ligament stretching je, perut kita expand so fast dalam 2nd tri, saraf2 dan urat pun kena stretch, jadinya mcm eletrik gitu atau shooting pain here and there, especially bila kita gerak suddenly atau usap bawah perut. Normal je, tapi since ni 2nd pregnancy after miscarriage, best you mention this to your doctor next checkup just for peace of mind, tak apa pun, just to confirm everything's progressing well. Enjoy the relief from morning sickness, and hang in there mama, 2nd tri's usually the easiest part!
